HoIsTme APPARATUS.

SPECIFICATION forming part of Letters Patent N o. 377,465. dated February '7, 1888. j A* Application filed March 17, 1887.

To all whom it may concern.-

Be it known `that I, MARTIN Sp. RAGSDALE, a citizen of the United States of America, residing at Freelandville, in the county'oi` Knox and State of Indiana, havev invented certain new and usefullmprovements in Hoisting Apparatus, of which the following is a specication, reference being had thereinv to the accompanying drawings.

My invention relates to an apparatus for hoisting. It is intended to be used for hoisting and Ysuspending wagon-beds in sheds, or to unload them into cribs; to suspend live animals for any purpose-as to shoe those that are unruly or to operate on those that are injared-and to hang slaughtered animals for convenience in cleaning andcutti'ng. It is espeoially designed to furnish farmers with a cheap and easily-operated hoisting-machine.

' l The whole apparatus is shown in Figure 1 of the drawings, a pawl-and-ratchet device in Fig. 2, and a hook in Fig. 3, the same letters referring to the same parts in the several iigures.

The apparatus consists of a Windlass, B, .whose bearings rest in and rotate on the framework, A, and which is fitted with areel, O. To this reel are fastened, and about it are wound, four ropes, D, for hoisting. These may be of wire, hemp, or other material, and so arranged as to ascendand descend together. From the reel the ropes pass over four rollers or pulleys, E, which are supported on theframe-work, and from these pass down to the load. To the .free ends of these. ropes are attached hooks F, with which to take hold ofthe wagon-bed G or other load.

To the lwi-ndlass, near one of its bearings, is attached a lever-bar, H, by means of which'the windlass is to be rotated. Connected to and operated with the lever-bar is an attachment, I, consisting of a handle withv an elbowcurve, a, connecting-rod b, spring c, and pawl d, the latter tting into a semicircular ratchet-plate, K. This attachment in its several parts and operation is shown in Fig. 2. The plate is fastened against the frame-work which supports the apparatus, and the handle, spring, and

pawl are so pivoted on the lever-bar that by engaging or disengaging the pawl the wind- `lass may be held or released, as desired. This semIN0.231,294. (No milder.)

handle and its appurtenances, including the ratchetplate, are of metal, while the windlass and lever-bar are of wood.

In'the upright piece of the frame-workv L u and along theside piece, M, the latter of which is placed for the purpose, are arranged a series of holes adapted to receive a movable pin, O, to engage the lever-bar and hold th any desired elevation.

In Fig. l N represents, the 'standards cfa" wagon, from which the bed ishoisted.

From this description of parts, their con nections and uses, it will be seen that any 65 movement of the lever-bar rotates the windlass and hoists or lowers the load. It will also be seen that the pawland-ratchet device and the adjustable pin are each adapted to-hold the l windlass inany desired position, and each supplements the other. If the pin is not in reach,i

the pawl 'and ratchet will Vhold until it is recovered and placed; and if the ratchet device y 'e s should become deranged the pin will hold.

I am aware lthat the windlass, bar, ropes,

pawl and ratchet, and hook are `common dey vices, and I do not claim the inventionofany of them; neitherdofl claim a combination of them ina machine in which avpawl and ratchet is used torotate the windlass,for in which the 4 windlass is rotated by a crank with pulley and cords. ,l

What I claim-as my invention, and desire to secure by Letters Patent, is-

A hoisting-machine comprisingfa win'dl'ass,

with a vlever-bar by which to rotate it, ropes wound around the windlass and descendingto l load at the load,y pulleys supported on. the frame work, over which the-ropes pass, hooks attached to the ends of the ropes, an attachment pivoted on the lever-bar, consisting ofa curved handle, rod, spring, andpawl, a ratchet-plate fastened to the frame-work,the pawl, and a' pin adapted to fit into holes' arranged along the framefwork, all combined, arranged, and f operated substantially as set forth.

In testimony whereof I affix my signature in preseneeof two witnesses.
